There's so many times when I wish I was able to order from Newegg.
Not saying this would necessarily be one of them, but it's annoying to always have to pay the amount in Euros + shipping to backwards Macedonia + customs.

okay, you guys do know that if you buy the samsung 840 its totally not worth it?
the new 840's are TLC:http://www.centon.com/flash-products/chiptype
they will last 1/2 the time as the old MLC and the write speed is MUCH MUCH lower than the old 830's ~ 100MB/s slower.
IOPS are higher yes but life lasts half of the older gen.
HOWEVER,
the new 840 PRO's have much better stats than the 830's
but is 80 dollars additional is worth just:
20,000 IOPS increase
20MB/s read
60MB/s write?
You can get 830's for 70, so unless pro's sell for 100/90 on sale, it probably will never be worth it IMO.

Not all MLC chips can endure 10k PE cycles; IIRC the 830 chips are produced along with 3k PE rated intel chips. Also that's only inherent to the NAND chips, there are various other technologies in play that help to extend the life of the chips. There's an 830 that's cycled through petabytes of data on the Xtremesystem forums despite the supposed 3k PE cycle rating. Chances are the Samsung 840 has improved upon the tech in the 830, so I don't think you can say longevity will be a real issue unless it's empirically measured with several sets of samples.

Sequential speeds aren't really what make SSDs fast and most people won't be worried about sequential write. The ones that are will probably be getting the pro for a number of reasons. But sequential read is faster on the 840 according to reviews anyway.

If you can get the 830 cheaper I'd still get it. Prices are dropping since stores are probably trying to spare up room in inventory for the new 840 and 840 Pros.

One last thing, the 250GB 840 has a MSRP of $200 so Newegg is misrepresenting the original price. The deal isn't that great
